Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
6-(2-Fluorophenyl)-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazole (CAS 876884-51-4), molecular formula C9H5FN4S and molecular weight 220.23 g/mol, is a CATO reference standard with documented purity and traceability.
6-(2-Fluorophenyl)-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazole (C9H5FN4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 6-(2-Fluorophenyl)-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
